Defensive publication

ABSTRACT

THE PARTICULAR TWO-PHASE GLASS SYSTEM IS COMPOSED OF 50-70% BY WEIGHT OF A HIGH MELTING GLASS AND 30-50% OF A LOW MELTING MOBILE METALS AND THE TWO-PHASE GLASS SYSFINELY DIVIDED NOBLE METALS AND THE TWO-PHASE GLASS SYSTEM ARE PROUDCED, AND WHEN FIRED WILL YIELD SMOOTH RESISTORS HAVING LOW CONTACT RESISTANCE AND LOW NOISE VALUE.

DEFENSIVE PUBLICATION UNITED STATES PATENT OFFICE Published at the request of the applicant or owner in accordance with the Notice of Dec. 16. 1969, 869 O.G. 687. The abstracts of Defensive Publication applications are identified by distinctly numbered series and are arranged chronologically.

Defensive Publication applications have not been examined as to the merits of alleged invention. The Patent Ofiice makes an assertion as to the novelty of the disclosed subject matter.

PUBLISHED MAY 11, 1971 T886,013 TWO-PHASE GLASS SYSTEMS AND RESISTOR COMPOSITIONS CONTAINING THE SAME Kenneth E. Schubert, Wilmington, DeL, assignor to E. I. du Pont de Nemours and 'Company, Wilmington, Del. Continuation of application Ser. No. 679,525, Oct. 3, 1967. This application July 8, 1970, Ser. No. 56,156 Int. Cl. H01b 1/02 US. Cl. 252-514 No Drawing. 11 Pages Specification The particular two-phase glass system is composed of 50-70% by weight of a high melting glass and 30-50% of a low melting glass. Resistor compositions composed of finely divided noble metals and the two-phase glass system are produced, and when fired will yield smooth resistors having low contact resistance and low noise value.
